Description
While no P- or CP-violation has ever been observed in the strong
sector of the Standard Model, there is no first principles reason
for it not to be present. Theoretical calculations have shown the
possibility of P-violating bubbles in the QCD vacuum, which in
combination with the strong magnetic field created in off-central
heavy-ion collisions leads to the Chiral Magnetic Effect (CME).
In addition, a coupling between the CME and the related
Chiral Separation Effect produces a wave-like excitation called
the Chiral Magnetic Wave (CMW). The CMW produces a quadrupole
moment that always has the same sign and is therefore present in
an average over events. In this talk we present a series of
charge-dependent anisotropic flow measurements in Pb-Pb
collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV in ALICE. The relation of these
measurements to the search for the CMW is discussed.
